[C++-sig] conversion problem
My authomatic conversion function from std::pair does not work when one of the pair type is a boost::python::object. Template for conversion template struct pair_to_tuple { typedef pair_to_tuple converter; typedef std::pair ctype; static PyObject* convert(ctype const& v) { using namespace boost::python; return incref(make_tuple(v.first,v.second).ptr()); } static void register_to_python() { boost::python::to_python_converter(); } }; using namespace boost::python; pair_to_tuple::register_to_python(); <- FAILED pair_to_tuple::register_to_python(); <- OK The error I get is *error C2668: 'boost::python::make_tuple' : ambiguous call to overloaded function could be 'boost::python::tuple boost::python::make_tuple<_Ty1,_Ty2>(const A0 &,const A1 &)'** or 'boost::tuples::tuple boost::tuples::make_tuple<_Ty1,_Ty2>(const T0 &,const T1 &)' [found using argument-dependent lookup] * What I'm I doing wrong?* * ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
[C++-sig] preventing boost::python::throw_error_already_set
hi everyone, i'm having a problem where a boost::python::throw_error_already_set is being thrown and causes a segfault (linux). unfortunately the error happens from within python, when reaching the end of an iteration through a vector array, which was exported using the vector indexing suite. is there any possibility to catch the previous exception? ___ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig

That's hard to tell without more context: Who is doing the iteration, for example ?
